The quickest way to revert to effective stock is to use the 'unroot' option in the SuperSU app.ĭue to the fact that I am currently unable to get custom recoveries booting, I am also unable to build TWRP or CWM for the device, which severely limits custom ROM options. If you are going to hack your hudl 2, be extremely careful. I'm not sure if this is a bug or intentional, but it's certainly not helpful. Powering on with volume up and down buttons pressed produces a message on screen saying 'entering bootloader', but the bootloader (at least in the form accessed via 'adb reboot bootloader') is never reached.
The recovery image can be loaded by powering on with the volume up button held, but this will only flash zip files signed with a key we do not have. Droidboot, which is used to flash the device for this root, is only accessible via 'adb reboot bootloader'. If the device won't boot (perhaps due to a problem on the system partition) and ADB is not available, then there is no way to recover. I will continue to investigate alternative approaches.Īs I found out with my first bricked device, hacking around on the Hudl 2 is dangerous. Granted, it's not the ideal way to root but for now, it works. It is completely stock apart from the addition of Chainfire's SuperSU root application. With this in mind I have instead built a custom system image for flashing via fastboot. My attempts thus far to create custom recoveries have failed to boot, which is unfortunate. Unfortunately this is not an option either - although fastboot flash is supported on the device, the recovery partition appears to be checksummed in some way.
The second option is to build a custom recovery that allows flashing of update zips, which is flashed using 'fastboot flash'. Unfortunately this is not possible on the hudl 2 as the 'fastboot boot' functionality is stubbed (not available). The first is a 'superboot' image, which is loaded via fastboot and automatically roots the device. Normally when I create a root solution I prefer to use one of two approaches. The hudl 2 is great, but it's too thin to make a particularly good doorstop. If you attempt to use this root solution on a version other than that detailed above, there is an extremely high possibility you will brick your device.
Your Hudl2 MUST be running software version '20140924.194555' or '20141009.191216', detailed at the bottom of the 'Settings -> About' screen. To use this root solution you need a Hudl2 (obviously), a Windows, OSX or Linux computer and a microUSB cable. What you need in order to use this root solution
It is advised that you do NOT install any OTA files without checking here first that it is safe to do so! Failing to follow the steps correctly could lead to your device being rendered completely unusable (bricked). If you don't feel confident following the steps in this post, do not proceed.īefore you start, read through all of this post. You should be aware that rooting your device may void the manufacturer's warranty and is a risky operation. MoDaCo / I take no responsibility should anything bad happen to your tablet, regardless of how / why it happens.
